APPARATUS FOR TREATING EMULSIFIED OIL.

Application filed September 1, 1920, Serial No. 407,418. Renewed May 28, 1928.

5 distillation under a vacuum. The object of the invention is to provide an improved apparatus which is mechanical of construction and which is able to withstand a considerable vacuum pullwhile at the same time permit- Inthe drawing: a v Fig. 1 is a view in side elevation, with parts broken away, showing an "apparatus constructcd in accordance with. my invention.

Fig. 2 is a view, in reduced size, of the fur nace and stills shown in Fig. 1.' I e Referring to the drawing, '1- designates the firebox, provided with stack, 2. In this firebox is mounted the still, 3, which still 3,

consists of a plurality of superimposed shells or sections, 4 and 5,'connected to each other by the conduits, 6. There can be any-desired number of these superimposed sections. By making this still in sections of the character shown, the still can more efie'ctively withstand the vacuum strains. charged into'the still through charging line, 7, having valve, 8, and connected to suitable feed pump (not shown). The residue maybe drawn oif through line, 9, having control valve, 10. The vapors pass out of the top of the uppermost section through vapor line, 11, connected to water condenser coil, 12, seat ed in water condenser box, 13. The condenser coil leads to the top of receiver, 14, which receiver, 14, is provided with liquid level gauge, 15, and pressure gauge, 16. Water is drawn 01f through the lower part of the receiver through pipe, 17, having valve 18, connected I 40 to suction pump, 19. Oil is drawn ofi of the receiver through pipe, 20,having valve, 21, and connected to a similar suction pump, 22.

A vacuum is maintained in the entire system by means of the vacuum pump, 23, connected by pipe, 2 1, having valve, 25, to the top of the receiver, 14:. r

' The still is heated by means of the burners, 26,. which extend longitudinally along the sides of the still and are slotted at their inner 5o faces'as shown at 27. In the construction shown there are four pairs of superimposed burners. The arrangement is such that any Oil may be pair of burners may be used independently of the others. The still may be initially charged up to the level of the uppermost pair of burners and there subjected to surface distillation while at the same time maintaining a vacuum on the system. As the level of the oil lowersthe'uppermo'st pair of burners may be shut off and the pair next below used and so on, as the liquid level in the oil decreases.

Q By means of this arrangement it will be posunderstood that these burners extend on the ous'ide' of the'stilladjacent the walls thereof.

- I'claim as my invention:

1. An apparatus for treating emulsified oil, comprisinga still composed of superimposed interconnected horizontal cylindrical sections, meansfor supplying oil to the upper of'said cylindrical sections to substantially fill the still means for heating the surface of the body of oil in the still irrespective of the quantity of oil therein, said means comprising a plurality of pairs of horizontally disposed burners positioned outside of the walls of said cylindrical sections; in different vertical planes for. applying heat to the sides of said sections, means for independently controlling the surface of the oil-continuously as'the body of oil decreases and the surfaceof the oil in the still'becomes lower.

2. apparatus, for treating emulsified oil comprising a still composed of vertically disposed parallel sections, means for supplying oil to the upper section, means for heating the surface ofthe oil in the still regardless of the quantity of oil therein, said means comprising pairs of vertically. spaced, horizontally disposed burners positioned exteriorly of the still, means for independently controlling said burners whereby heat may be applied to the surface of the oil continuously as the. body of the oil in the still decreases and the surface lowers,
